I'm down to my last Michelin Pro2 Race tire, and about to buy some new tires. Before "flaming", I DO know that Michelin is up to the Pro4 Race model. I'm looking for those of you that have experience with the Pro3 Race, AND the Pro4 Race tires. I've read more than one complaint about the Pro4 tires that they are prone to puncturing, and that sorta scares me. Looking for some opinions on either, or both models. Thank you!
